Head, Probe and Sample Preparation
70 MultiMode SPM Instruction Manual Rev. B
Other chapters in this manual describe how to perform specific types of imagery. The table below
outlines where you will find additional information for each type of imagery. If you are new to
SPM and want to practice, we suggest you begin with contact AFM in Chapter 6.
This instrument uses a semiconductor diode laser emitting a maximum 1.14mW beam at 690nm.
The light is emitted downward and normally reflects back into the system’s optics from the back of
the cantilever probe. Note that the laser is powered when the SPM head is plugged into the
microscope’s support ring and the Mode switch is set to either AFM & LFM or TM AFM
(TappingMode). (As a safety precaution, the MultiMode SPM head features an internal switch to
shut power off to the laser when the head is tilted. Operators should use care, however, to avoid
staring into beams reflected from sample surfaces).
